i? "The Schedule referred to in these Letters Patent and making partici' the sam e.

Be it known -that I, A. BRINCKMANN, of New York, in the county of New York, and State of New York, have invented a newSelf-Closing Faucet; and I do hereby declare that the following is a full, clear, and `exact description tl1ereof,"wl1ich will enable others skilled in theatt to make and use the same, reference being had. to the accompanying drawings, 'forming part of this specification, inwhichr Figure 1 represents a side view of my improved faucet.

Figure 2 is a plan or top view, partly in section, of p the same.

Similar letters 'off reference indicate. corresponding This invention relates to a new faucet for waterpipes and other purposes, which is to be self-closing, so that-no liquid 'can be lost by accidentallyleaving the faucet open. r A

The invention consists inattaching a weighted lever to the spigot of the faucet, which lever will always autoinatically draw the faucet closed, and which will also serve as a handle for` opening the faucet; in the application tothespigot of` a spring concealed in an adjustable cap, whereby the spigot is drawn tight into its seat, to' prevent leakage; and in providing notches in the edge of the shoulder, upon which the cap holding the spring is screwed, and a set-screw in the cap, so that the cap` can be locked by the screw in `one of the notches, in' such manner that the spigotwill work more or lesshard, to cause the weight to close it more or less quick. This is important, as on pipes where there is no greater pressure, the cock should be closed slower than where there isbut slight pressure, in order to prevent injury to the pipe by too sudden stoppage of the moving column of water. 1 A, in the drawing, represents the tubular body of a faucet..

B is the horizontalspigot of thesame. The spigot is conical, as` usual, and is held tight `at dd, in iig. `2, and by dotted lines in fig. I, and a set-screw, e, is turned into one of the notches, to prevent the cap from being turned, afterit has once been adjusted, to impart to the spring a certain desired power. p i

E is a handle, secured to the horizontal spigot, by which the samecan be opened or closed.

A weight, F, is secured to the end of -the handle E. This weight Iwill have the tendency to keep the faucet closed, and to close' it automatically when open.

It isv evident that when the spring a. is more compressed, the weight will close thev spigot slower than if the'spigot works quite loose. The. cap is therefore to be set by the screw e, to adapt the time of closing to any suitable pressure ot' liquid.

Much loss of water will, `in cities, be prevented by the use of this faucet, as the same can never be accidentally left open. rlhe screw-cap can -be omitted if', by other equivalent means, the power of the spring cau be adjusted.

Having thus described my invention,

` I claim as new, and desire to secure by Letters Patentv v p v'lhe faucet, constructed as described, with the sprin g shoulder b, adjustable screw-cap G, notched plate e, provided with a screw-thread upon its edge, the setscrew e, and weighted handle E, all arranged substantially as described, for the purpose specified.U
